This beautiful lamp looks like a regular 18cm twist-top jar by day - but lights up with a spectacular rainbow effect in the dark! When placed in bright sunshine, the clever solar panel in the lid charges up the battery. This energy is then used to power the LED light inside, lighting up automatically in the dark. With a gentle glow, the lamp cycles through six soft colours for up to 8 hours on a single charge. A cool eco-friendly gift to brighten your day!
